cis-acting DNA sequence found in controlling region of some prokaryotic gene. In the lac operon, the operator is bound by lac inhibitor to block transcription.
The DNA sequence where a repressor protein reversibly binds to regulate the activity of one or more closely linked structural genes.
A regulatory DNA sequence that controls the transcription of structural genes.
The region of a bacterial operon that binds repressor proteins to inhibit transcription.
A segment of DNA that interacts with a repressor protein to regulate the transcription of the structural genes of an operon.
A specific region of the DNA at the initial end of the gene, where the repressor protein attaches and blocks mRNA synthesis.
Short region of DNA in a bacterial chromosome that controls the transcription of an adjacent gene.
a short sequence of DNA where an active repressor binds, preventing RNA polymerase from attaching to the promotor and transcription therefore does not occur
The region of an operon that acts as the binding site for the repressor.
DNA site located between a promoter site and the structural genes of an operon. A repressor protein binds to this sequence of DNA and blocks the initiation of transcription.
a chromosomal region capable of interacting with a specific repressor, controlling the functioning of adjacent cistrons
The nucleotide sequence to which a repressor protein binds to prevent transcription of a gene or operon.
A DNA region at one end of an operon that acts as the binding site for repressor protein.
Very short base sequence between a promoter and bacterial genes; a binding site for a repressor that can block transcription.
Short DNA sequence in a bacterial or viral genome that binds a repressor protein and controls transcription of an adjacent gene. ( Figure 10-2)
